Is this your first time submitting a feature request?

• I have read the expectations for open source contributors
• I have searched the existing issues, and I could not find an existing issue for this feature
• I am requesting a straightforward extension of existing dbt functionality, rather than a Big Idea better suited to a discussion

Describe the feature

Context:

• [FEAT] Support Snowflake identifier references when QUOTED_IDENTIFIERS_IGNORE_CASE=True dbt-fusion#496
• Snowflake ignore case docs.getdbt.com#7698

If set, dbt-core should successfully parse the project, rather than raising a validation error (as it does currently):

% dbt parse
16:05:30  Running with dbt=1.10.6
16:05:30  Encountered an error:
Runtime Error
  at path ['quoting']: {'snowflake_ignore_case': True} is not valid under any of the given schemas

Describe alternatives you've considered

Not supporting this. Anyone who starts trying their project on Fusion, who needs to set quoting.snowflake_ignore_case: True, can no longer parse the same project with dbt Core.

This is not what we want. Net-new features in the dbt Fusion engine that require different project code should no-op in dbt Core, even when the feature itself is not supported in the Core engine.

Who will this benefit?

Users migrating their projects from dbt Core to Fusion
